China has launched the world's first satellite dedicated to testing the fundamentals of quantum communication in space. The $100m Quantum Experiments at Space Scale (QUESS) mission was launched today from the Jiuquan Satellite Launch Center in northern China at 01:40 local time. For the next two years, the craft – also named "Micius" after the ancient Chinese philosopher – will demonstrate the feasibility of quantum communication between Earth and space, and test quantum entanglement over unprecedented distances.
History will note that the guy who discovered liquid water on Mars was an undergraduate at the University of Arizona, a 20-year-old who played guitar in a death-metal band and worked in a planetary science lab. One day, while comparing different satellite images of a single Martian crater taken at various times of year, he noticed something odd: a set of dark streaks in the soil that grew in the Martian summer and shrank in the winter. They seemed to flow down the crater’s slope, like a spill.
Toward the end of last year, the people behind the Large Hadron Collider announced that they might have found signs of a new particle. Their evidence came from an analysis of the first high-energy data obtained after the LHC's two general-purpose detectors underwent an extensive upgrade. While the possible new particle didn't produce a signal that reached statistical significance, it did show up in both detectors, raising the hope that the LHC was finally on to some new physics.
Your taste in music is weird. Maybe you just can’t stop listening to that power ballad, or you’ve wondered about your bewildering weakness for yodeling. And maybe, just maybe, nobody understands your all-consuming obsession with Steely Dan, the greatest band of all time.
Scots experts have discovered the brain’s “rhythmic fingerprints”, which could be used to diagnose and treat conditions ranging from post traumatic stress disorder (PTSD) to dementia.
Brain oscillations – often known as brain waves – caused by electrical waves pulsing through grey matter have puzzled experts since their discovery by German psychiatrist Hans Berger in 1924.
Neuroscientists from Glasgow University have now found that each area of the brain has its own characteristic mix of rhythms, which could be read like a fingerprint using magnetic waves.
